Abstract (en)
A digital television system comprises a communication network bus, a television connected to the bus, a decoder, a signal source connected to the bus, and a CA module. Communication between apparatuses connected to the bus thereby takes place according to a certain protocol. The CA module is connected to said bus, and the communication between the signal source, the CA module and the television or the decoder takes place via the bus. This obviates the use of special connectors for connecting the module to the television or to the decoder. In addition, two or more CA modules can simply be connected to the bus, and each CA module can be used by several signal sources and/or decoders.
